Scratch resistance tester

Scratch resistance tester

Product Introduction:

Used to evaluate the cutting, scratching, planing, scraping, and carving properties of materials. Its application areas include: rigid organic materials, plastics, glass, and so on. The scratch testing machine for artificial boards is used to test the scratch resistance of material surfaces. It is developed for testing the scratch resistance of various types of artificial boards and decorative artificial boards. It can meet the requirements of GB/T17657-1999 "Test Methods for Physical and Chemical Properties of Artificial Board and Decorative Artificial Board" and conduct "scratch resistance performance measurement" tests. It is an ideal testing equipment for quality inspection departments and artificial board production enterprises at all levels, and can provide you with accurate test results.

Scratch tester application:

Taber 551 is used to evaluate the cutting, scratching, planing, scraping, and carving properties of materials. Its application areas include: rigid organic materials, coating adhesives, powder coatings, anodized materials, soft metals, plastics, glass, and so on. It can also be used to test the adhesive quality of the same material, protective coating, and the ultimate performance of similar materials. Taber 551 is easy to operate and easy to move, and can test materials that are 1/2 "to 4" thick, square or circular.

Scratch tester operation:

Before installing the sample, it is necessary to adjust the scale to the appropriate height based on the thickness of the sample. Install precision cutting tools on the scale and place them on the sample. Start the instrument and rotate the turntable at a constant speed to ensure accurate measurement results. By changing the load of the cutting tool, you can evaluate the material's shear or scratch resistance performance.

The design of the weighing rod of the instrument allows it to be level with the sample and turntable, and can be raised or lowered according to actual needs. In addition, the weighing rod can also be lifted and suspended in the air to facilitate the operator's removal of the sample. By changing the position of the sliding weight, the total load on the sample can be adjusted within the range of 0-1000g. Cutting tools can choose to use tungsten carbide cutting tools or conical drilling stones.

The test results can be visually judged using a randomly equipped 10x magnifying glass, and users can also observe using a high-precision optical microscope.

Dry state flocculation performance tester

Product model:

G275

Applicable scope:

The dry state fluff tester, also known as the twist tester, is a specialized equipment used to evaluate the fluff shedding performance of non-woven fabrics under dry conditions. It is mainly suitable for evaluating the shedding performance of non-woven fabrics and other textile materials used in medical protective materials (surgical sheets, surgical gowns, clean clothes, etc.). When testing, the testing principle is that the sample is subjected to a combined effect of torsion and compression in the test chamber. During this twisting process, air is extracted from the test chamber and the test results are evaluated by counting and classifying the particles in the air using a laser dust particle counter.

Principle:

The sample undergoes a combined effect of torsion and compression in the test chamber. During this twisting process, air is extracted from the test chamber, and particles in the air are counted and classified using a laser dust particle counter.

Meets standards:

YY/T 0506.4, ISO 09073.10

Product parameters:

1. Sealed torsion chamber and air mobile phone

2. Twisting speed: 60 times/minute

4. Sample fixture: 82.8mm

5. Laser particle counter testing range: Collect samples ranging from 0.3 to 25.0um

6. Laser particle counter flow rate: 28.3L/min, ± 5%

7. Sample testing data storage: 3000 pieces

8. Timer: 1-9999 times

Test environment:

Level 5 cleanroom (i.e. level 100 purification environment)

Main components

1. Dry state floc generator

1) Twisting device: a device that exerts a comprehensive effect on the specimen, including twisting, compression, and resetting

2) Twisted box (anti-static): An organic glass box that can resist static electricity and cover the twisting device for testing

3) Air collector: a sampling port with a certain shape fixed in a specific position in a twisted box

2. Laser dust particle counter

Count and classify the particles in the collected air
